' ,EYEGLASSES.

T0 on whom it concern: 7

Be it known that 1, ROBERT S. BIhgiIR, residing at New Rochelle,- in thecounty of VVes tchester and State of New York, have invented certain new and useful Ini rovementsin Eyeglasses, of-which the fol owing is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to eyeglasses,

One of the objects thereof is to provide a device of the above type of simple and practical construction and eflicicnt action in use.

Another object is to provide a device of the above type adapted to resist accidental dislodgment and evade tendency thereto."

Anotherobject is to provide simple and inexpensive means in connection with glasses of the type first mentioned adapted torender the same more comfortable to the wearer and to retain the same more securely in position.

Another object is toprovide means connected with glasses of the relatively rigid frame type, whereby their construction is simplified and their cost of manufacture re.- duced.

Other objects will be in art obvious and in part pointed out hereina ter.

The invention accordingly consists in-the features of construction, combinations of elements, and arrangements of parts, which will be exemplified in the embodiments hereinaf ter set forth and the scope of the application of which will be indicated in the following claims.

In the accompanying drawings, wherein are shown one or more of various possible embodiments of the several features of my invention, Figure l is a perspective view of a portion of one of the same. Fig. 2 is a plan of the same.

Manyglasses are so constructed as, upon the lens being brushed in this direction to tend to sepa Specification of Letters Patent. Application filed: October 26,1906. Serial No. 340.645.

rate-the -nosespads and loosen the hold upon the nose.

v It; may also befioted that rigid? frame glasses are often considered objection able by reason of their somewhat involved construction, tending to high first cost. and a difliculty to maintain the same in repair. It may also be noted that in connection with nose-engaging members or pads it is desirable that a given intensity of pressure should provide as large an engaging surface asis'prac ticable, as in this manner a secure'hold upon the nose'isbe'st insured. The above and other defects are remedied and the above and other advanta es attained in constructions of the nature of that hereinafter described.

Referring now to ,Fig. 2 of the accompanying drawings, there are shown lenses 1 and 2, the latter of which is mounted in aholder 3 in rigid. relation .to the bridge 4. Secured upon the bridge adjacent lens 2 is a lever 5,

provided with a nose-pad 6, the construction of 'lwhich will hereinafter be described in de- .tai

Lever 5 is mounted upon the bridge, as by means of a screw 7, in such manner as to be clamped thereto at anydesired angle, and 'thus provide an attachment at this point. This lever, moreover, isso formed and constituted as to adaptthe same to be bent slightly to accomplish small adjustments, and thus to a certain extent do away with the necessity for the. em loyment of the screw'7 At the opposite en of the bridge 4 there is pivotally mounted upon the pin 8 a lever 9,] provided with a nose-pad 10 and adapted to swing with relation to the brid e,

the inward limit of this movementbeing etermined by lug 11. Likewise journaled upon pin -8 is a ens-holder 12, adapted to permit the lens to swing outwardly from the corresponding eye,but to be limited as to 5 inward'movement, as by the stop 13, in such manner as to maintain the lenses normally in; the same plane. I Lens-holder 12 is provided with an arm 14, normally disposed beneath a screw 15, tapped within the bridge beneath the lever 9. A spring 16, substantially of the form shown, is positioned upon the screw'15 and tends normallyto hold both the lever 9 and the lens-holder 12 against their respec-- tive stops.

The embodiment shown in Fig. 3 of the drawings differs from that above described mainlyin that the lenses upon both sides are movable, as immediately above set forth, and the construction last described with ref- :be desired to 1 necessary to change t o y raw'mg inwardly 1;

outerend of lever 5. thus separated, so as to permit the glasses to forth, inasmuch as each I swinging outwardly to force inwardly the cor- '65 substantially ciear from t erence to. the modification shown in Fig. 2 obtains upon both sides in the modification shown in Fig. 3.

In order to aid in insuring a firm hold upon the nose with a minimum of pressure, a nosepad 17 is employed, which may be riveted to its supporting member, as shown. This nose-en aging member is preferably of sub stantial y the form shown, presenting a concave surface 18 to the nose, and is of such constitution as upon engaging the nose to tend to flatten out and exert a substantially uniform pressure over the relatively large area thereof. This type of nosei-ipad, as will be seen, admits of the same tting the nosesnugly Without previous adjustment to the wearer.

lThe operationof the above embodiments is substantiall as follows: Assuming-that it t the glasses shown in Fig. 2, the lever 5 is first ad usted either by loosening the clam 7 for large adjustments or by bending the ever for small adjustments, so as to properly position the nose-pad 6 to hold this side of the glasses inoperative relation to the nose. This adjustment oncebeing madeit will be obvious that it is unthe same for a? given laced upon the nose e outer end of the lever 9, as by drawing together the outer end offthis lever and the abutment formed by the The nose-pads are The glasses are be placed upon the nose, andvupon the lever being released the reaction of spring 16 tends to throw the pad 10 toward thenose, so as to grip the same and hold the glasses in opera-- tive position, This feature of my invention 0 is of value independent of its relation to the mechanism involvin the mountingof the lens 1. With the g asses in position upon the vface the lens 1 be brushed away from the corresponding eye it will swing .ward'ly su stantially freely, but will place "additional tension. upon the spring 16, tending to" force inwardly-the lever 9 andcause the nbsea 'grippmg action, which will abislodgment.

tion, the same action will obtain to a greater or iess extent, dues to the swinging of the lens 1 against t e corresponding e' e, whereby the same is bent outwardly an tensioned as above described, j

As many changes could be made in the above construction and many a parently widely-different embodiments of t 1s invention could bemade without departing from the scope thereof it is intendedthat all matter contained'i'n the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense;
